Well, it's possible and it's the downwind run I do most often. The route isn't a traditional downwinder where you launch from point A and finish at point B. It's actually an out and back - now before you jump on me for this not being a downwind route, my rationale is that it allows me to get in a nice downwind leg while the upwind portion is made much easier since a good chunk of it is in sheltered flat water. The route takes advantage of Toronto Island to provide shelter for much of the upwind legs. It's by far, the most convenient downwinder I do. A downwinder becomes something you can squeeze into your schedule rather than having to book much of the day for it.
Here's how it breaks down:
- Downwind: 3.5km
- Upwind in exposed rough water: 1.8km (just half the downwind distance!)
- Upwind in sheltered water: 2.8km
- Total: 8.1km with a 200m portage
The launch is just a few minutes away from downtown Toronto at Cherry Beach. It works great in SW or NE winds of 15-25mph. Beyond 25mph, the 1.8km of upwind legs in exposed waves gets challenging.
In a SW wind there are some pretty good sized waves on the first part of the downwind run along the south side of Toronto Island where the water is shallower. However, if the wind is SSW, expect reflected waves off the Island walls to confuse the waters there. Once past the Eastern Gap, the waves get a bit smaller until you finish at Cherry Beach.
One option for a longer paddle is to do a double loop of the Island without returning to Cherry Beach in between loops. This gives you proportionally more downwind distance relative to the exposed upwind paddling distance. It also doubles the most fun part of the run between Centre Island Pier and the Eastern Gap. Here are the stats on a single versus double loop run:
Single Loop Route:
Total distance: 8.3km (including 200m portage)
Portage: 200m (2.4%)
Downwind leg: 3.5km (42%)
Exposed Upwind Legs: 1.2 + 0.6 = 1.8km (22%)
Sheltered Upwind legs: 2.8km (34%)
Double Loop Route:
Total distance: 14.3km (including 2x200m portages)
Portage: 2x200m (2.8%)
Downwind legs: 2.3 + 3.6 = 5.9km (41%)
Exposed Upwind Legs: 1.2+ 0.6 + 0.6 = 2.4km (17%)
Sheltered Upwind legs: 5.6km (39%)
In NE wind, the reverse route can be done. The bumps are a bit smaller since there is less fetch and groundswell - although the waves get steeper as you approach shallower waters near the downwind finish at Centre Island pier. If you go in a NE wind, make sure you're confident that you can make it back home going upwind.
